I think slowly but surely people are excepting gasoline derived TATA cars.Prime example is Nano.Till date TATA have sold around 2 lakh petrol Nano,a unique record for them.You also have to remember that both Suzuki and Huyndai are making gasoline engines for the past 50-60 yrs,while TATA are relatively much younger in this field.Slowly but surely TATA will get there,when and how fast? Well let the Time be the best answer for this question.
Because of financial troubles, had to dispose off the car. I told him not to sell if for anything less than a lakh, but he sold for 80k, desperate , could've easily fetched 1L+. It was in such great condition.
